VRTX connect to Cisco 4500X

Hello

We have a Dell VRTX (R1-2210) connecting via one 10G trunk to a Cisco 4500X-switch. Our VLANs are 10 and 11. However, I am not able to transmit or receive anything.

The Cisco-switch have been set up by the networking guys, they say there is connection, but that my frames are not vlan-tagged. In their end the port mode is set to trunk. Here is my config:

config-file-header
v2.0.0.51 / ROS_800_080
CLI v1.0

spanning-tree mode mst
spanning-tree priority 45056

What am I doing wrong?

Thank you.
